Washing your vehicle with a power washer
Cleaning the ex terior of your c ar with a high-pressure
po wer washer is safe as long as y ou obser ve a few sim ple
rules.
- Before using the power washer, make su re you have read
and unders tood the WA RNINGS=>
& in "General info r­
ma tion" on
page 2 78.
- Always fo llow t he operat ing inst ructions fo r the powe r
washer.
- Make sure t hat the jet o n the spray hose produces a "fa n
shaped spray".
- Do
not hold the spr ay nozz le too close t o soft ma ter ials .
When cleani ng the vehicle wi th a p owe r w ashe r always follow the
operat ing instruct ions . T his applies part icu larly to the
operating
pressure
and the spraying distance. M ain tain a suffic ien t distan ce to
so ft mater ia ls such as rubber hoses and sound/vibration deaden ing
materials (particularly on the unde rside o f the engine hood). Do no t
use a jet wh ic h sprays water in a
direct stream or o ne that has a
rotating jet.
W ate r temperatu re s hou ld not ex ceed 140
°F (6 0 °().
& WARNING
Never wash tires with a jet that sprays water in a direct stream .
This could cause invisible damage to the tires and weaken them ,
even if the spray i s from a relatively long distance and for a short
time . Damaged and weakened tires can fail and c ause accidents
and personal injury .

Changing the engine oil
The eng ine oil and oil fi lter mus t be changed according to the mileage
(kilome ters) and t ime intervals specified i n your vehicle 's Warranty &
Ma intenance booklet . Do not exceed these interva ls - harmful
deposi ts from o ld engi ne oil can reduce engine pe rfo rmance and ca n
lead to expensive engine repa irs.
C hangi ng the oil at the recommende d interva ls is so very imp ortant
because the lubricating properties of o il decrease gradually during
normal ve hicl e use. If yo u ar e not sure w hen you have yo ur oil
changed, ask your author ized Audi Service Adv isor .
Under some circumstances the eng ine o il should even be changed
more fr eq uent ly. Chang e oil mor e of ten if you d rive mostly short
distances, operate the veh icle in d usty areas or mostly under stop­
and -go t raff ic condi tion s, or when you use yo ur vehicle where tempe r­
atures stay be low free zing po int for long periods.

Engine oil consumption
To provide effective lubr ication a nd cooling for interna l eng ine parts,
a ll in ter na l c omb ustion e ngines use some oil. Oil cons umption v aries
from engine to engine and may change over the life of the eng ine .
E ngines te nd to use m ore oi l dur ing the b re a k-i n period t han t hey do
after ward, when oil consumption has stab ilized. Depending on t he
way the vehicle is driven and the operatin g cond itions, oi l cons ump ­
tion ca n be up to 1 qua rt pe r 1,200 m iles
(I liter per 2 ,000 km).
Consumption may be higher withi n th e first 3,0 00 miles (5,00 0 km).
Under nor mal co ndi tions, the rate o f oi l consu mptio n depe nds o n oil
quality as well as viscosity, engine speed ( rpm), o utside tempe rature,
roa d condi tion s, the amou nt of o il d ilution caused by co nde nsed
water or fu el residue, and oxidation of the oil. O il cons umption may
increase wi th en gine we ar ove r time, un til repl aceme nt of worn
eng ine pa rts may become necessa ry.
Because of all these var ia bles, there is no standa rd o r "norma l" rate
of oil consumption .
We urge you to check the engine oil level at
regular intervals, preferably every time you fill the fuel tank, and
always before a long trip .
The oil pressure warning light
~ is not an indicator of low eng ine
oil level. If the warning light does not go out after starting, or
flashes while driving (above 1500 rpm), a buzzer will sound . It
indicates that the oil pressure is too low. Stop the engine immedi- _.,,

help buyers make relative comparisons among tires. The UTQG is not
a safety rating and not a guarantee that a tire will last for a prescribed
number of miles (kilometers) or perform in a certain way. It simp ly
gives tire buyers additional information to combine with other
considerations, such as price, brand loyalty and dealer recommenda­

Cold tire inflation pressure
Tire pressure affects the overall handling, performance and safety of a vehicle .
Fig. 24 1 Tire pre ssure
la bel: loc ate d on
d river 's si de B ·pillar
Tire pressure generally refers to the amount of air in a t ire that it
needs it to do its job and safely carry the combined load of the entire
vehicle and its contents . Tire pressure is measured in kilopascals
(kPa), the inte rnational measur ing un it and in pounds per square i nch
(PSI). Tire press ure is based in part on t he vehicle 's design and load
limit -the greatest amount of weight tha t the vehicle can carry safe ly
and the t ire si ze. The proper tire pressure is frequently referred to as
the "recommended cold t ire inflation pressure. " Air in t he tires
expands when the tire heats up because of internal friction when it
flexes in use . The tire p ress ure is highe r when the t ire has wa rmed up
than when it is "cold." It is the inflation pressure in a "cold" tire that c o unts . Therefo re, you should never let air ou t of a wa rm tire to
match "cold tire inflation pressure " recommendations . The t ires
wou ld then be underin flated and could fail suddenly .

Maintaining proper tire pressure is one of the most important things
you can do to he lp avoid sudden tire failure . Underinflated tires are a
ma jo r cause of sudden tire failure . Keep ing t ires at the right pressure
is a lso important fo r safe and responsive vehicle handling, t ract ion,
braking and load carrying.
Tire p ressures are particularl y important
when the vehicle i s being driven at higher speed s, and then e spe ­
cially when heavily loaded even with in the permissible load­
carrying capacitie s approved for your v ehicle .
The recommended tire pressures for your Audi depend on the kind o f
t ires on you r vehicle and the number o f passengers and/or amo unt of
luggage you will be transport ing .
The tire pressure label is located on the driver 's side 8-pillar . T he tire
pressure labe l lists the recommended cold t ire inflation p ressures for
the vehicle at its maximum capacity weig ht and tires that were on
•
your vehicle at the time it was m anufactured. .,

Tires and wheels -________________ f!ffl
If you wish to improve comfort when operating the vehicle at
normal load (up to 3 occupant s), you can adjust tire pres sures to
those specified for normal vehicle load . Before operating the
vehicle at maximum lo ad, you must increase the tire p res sures to
those specified for maximum vehicle load=>& .
Bear in mind that the tire press ure monitor ing system can only
mon itor the t ire pressu re s you h ave sto red . T he sys tem does no t
recogn ize the load cond it ion of your vehicle.
Th e effectiveness of t he tire pressu re monitoring system will be
impa ired if you store normal load pressu res but then operate the
vehicle at its maxim um loa d=> & . See the

& WARNING
Overloading a vehicle can cause los s of vehicle control , a crash or
other accident, serious personal injury, and even death.
• Carrying more weight than your vehicle wa s designed to carry
will prevent the vehicle from handling properly and increase the
risk of a loss of vehicle control.
• The b rakes on a vehicle that has been overloaded may not be
able to stop the vehicle within a safe distan ce.
• Tires on a vehicle that has been overloaded can fail suddenly
causing loss of control and a crash.
• Always make sure that the total load being transported -
including the weight of a trailer hitch and the tongue weight of a
loaded trailer -does not make the vehicle heavier than the
vehicle 's Gro ss Vehicle Weight Rating.
& WARNING
• Incorrect tire pressures and /or underinflation can lead to a
serious or fatal accident.
• Incorrect tire pressures and /or underinflation cause increased
tire wear and can affect the handling of the vehicle.
• Incorrect tire pressures and/or underinflation can also lead to
sudden tire failure , including a blowout and sudden deflation,
c ausing loss of vehicle control. •

• Place the air press ure gauge on the valve.
• The tire p ressures sho uld on ly be checked and adjusted wh en the
tires are cold. The slightly raised press ures of wa rm tires must not be

& WARNING
Incorrect tire pressures and/or underinflation can lead sudden tire
failure, loss of control, collision, serious pers onal injury or even
death.
• When the warning symbol appears in the instrument
cluster, stop and inspect the tires.
• Incorrect tire pressure and/or underinflation can cause
increased tire wear and can affect the handling of the vehicle and
stopping ability.
• Incorrect tire pressure s and/or underinflation can also lead to
sudden tire failure, including a blowout and sudden deflation,
causing loss of vehicle control.
• The driver is responsible for the correct tire pressures for all
tires on the vehicle. The applicable pressure values are located on a sticker on the driver's side B-pillar.
• Only when all tires on the vehicle are filled to the correct pres­
sure, the tire pressure monitoring system can work correctly.
• The use of incorrect tire pressure values can lead to accidents or
other damage. Therefore it is essential that the driver observe the
specified tire pressure values for the tire s and the correct pres­
sures for the function of the tire pressure monitoring system.
• Always inflate tires to the recommended and correct tire pres-
sure before driving off. .,_
